a) 10 m/s
b) 25 m
Explanation:
a)
The body is moving with a constant acceleration, therefore we can solve the problem by using the following suvat equation:
![v=u+at](https://tex.z-dn.net/?f=v%3Du%2Bat)
where
u is the initial velocity
v is the final velocity
a is the acceleration
t is the time
For the body in this problem:
u = 0 (the body starts from rest)
is the acceleration
t = 5 s is the time
So, the final velocity is
![v=0+(2)(5)=10 m/s](https://tex.z-dn.net/?f=v%3D0%2B%282%29%285%29%3D10%20m%2Fs)
b)
In this second part, we want to calculate the distance travelled by the body.
We can do it by using another suvat equation:
![v^2-u^2=2as](https://tex.z-dn.net/?f=v%5E2-u%5E2%3D2as)
where
u is the initial velocity
v is the final velocity
a is the acceleration
s is the distance travelled
Here we have
u = 0 (the body starts from rest)
is the acceleration
v = 10 m/s is the final velocity
Solving for s,
![s=\frac{10^2-0^2}{2(2)}=25 m](https://tex.z-dn.net/?f=s%3D%5Cfrac%7B10%5E2-0%5E2%7D%7B2%282%29%7D%3D25%20m)
<span>The amount of solar energy available varies by location on earth, the time of the day at that location, the season and weather conditions. Rain, fog, and clouds will lower the amount of solar power available to gather and there are fewer hours of sun available in different seasons (winter for North America). To gather solar power, you also need a large area. This can be lessened by conditions such as snow, so that even on a sunny day, covered panels will collect less energy.</span>
Answer:
you absolute buffoon Use Ohms' Law: V = RI
V = (1x10^3)(5x10^-3) = 5 volts
Yes, this is in the range of normal household voltages.
Explanation:
125 because f=ma so you would use 100=mx0.75
Answer:
True
Explanation:
A convex mirror is a mirror whose outer bulging surface is the reflecting surface.
A convex mirror is used to see the distant objects and the image formed by the convex mirror is always erect and small. So, it is used as the rear view mirror.
It always forms a virtual, erect and diminished image of a real object.
It never forms a real image of a real object.
